A pair of broadband 90-deg. hybrid couplers are suitable for splitting and combining signals over broad frequency ranges through 26.5 GHz. Model 3014265 provides frequency coverage from 1.4 to 26.5 GHz while model 3014265 features outstanding performance from 1.4 to 26.5 GHz. The lower-frequency model 3014265 suffers less than 3-dB insertion loss from 1.4 to 26.5 GHz with better than 13-dB isolation between ports. It achieves amplitude unbalance of ±1.2 dB across the full frequency range with phase unbalance of typically ±12 deg. The maximum VSWR for this 3-dB hybrid coupler is 1.80:1. The higher-frequency model 3017265 has less than 3.4-dB insertion loss from 1.7 to 26.5 GHz, with better than 14-dB isolation between ports. It offers amplitude unbalance of ±1.5 dB and phase unbalance of ±10 deg. The maximum VSWR for model 3017265 is 1.85:1. Each of the hybrid couplers handles 20 W average power and 3 kW peak power across operating temperatures from –54 to +85ºC. Model 3014265 measures 2.62 x 1.00 x 0.49 in. while model 3017265 measures 2.60 x 0.625 x 0.50 in. They are both supplied with SMA female connectors but available with Type N female connectors as an option.
